I see what's going on: before my patch, ia64*-*-hpux* would use
tmake_file="ia64/t-ia64 ia64/t-hpux"
The former has
LIB2ADDEH = $(srcdir)/config/ia64/unwind-ia64.c $(srcdir)/unwind-sjlj.c \
$(srcdir)/unwind-c.c
the latter
LIB2ADDEH = $(srcdir)/unwind-c.c
overriding the ia64 default.
Unfortunately, I got the ordering wrong in libgcc:
tmake_file="ia64/t-hpux ia64/t-eh-ia64"
To fix this, ia64/t-eh-ia64 can go completely. This should restore
things as they were before.
